时空通常被看作是一个舞台，演员们以有质量和无质量的物质的形式在舞台上移动。在这项研究中，我们将探索这张照片之外的东西。出发点是观察到量子场涨落的时空距离越短，它们的相关性就越强。因此，时空距离的概念可以用相关强度的概念来代替。这表明了一个新的图片，其中抽象的2点和多点相关性是主要结构，一个图片，这是基本上是信息论。在低能区，时空和物质的次级概念将作为抽象的平行子的近似表示出现，即以弯曲时空的费曼规则的形式出现。
Spacetime is conventionally viewed as a stage on which actors, in the form of massive and massless matter, move. In this study, we explore what may lie beyond this picture. The starting point is the observation that quantum field fluctuations are the more strongly correlated the shorter their spacetime distance. The notion of spacetime distance can, therefore, be replaced by the notion of correlation strength. This suggests a new picture in which the abstract 2-point and multi-point correlations are the primary structure, a picture which is essentially information-theoretic. In the low energy regime, the secondary notions of spacetime and of matter would then emerge as approximate representations of the abstract correlators, namely, in the form of Feynman rules on curved spacetime.
